Mixed cation 2D perovskite: a novel approach for enhanced …

The integration of thin 2D perovskite layers at the 3D PVK/HTL interface is known to improve the power conversion efficiency and stability of perovskite solar cells (PSCs). In this work, we report a novel approach consisting of mixing two alkyl-based cations that form 2D perovskites (propylammonium iodide (P Sustainable Energy &; Fuels Recent HOT Articles

A high-performance all-metallocene-based, non-aqueous …

Here, a class of organometallic compounds, metallocenes, are explored to serve as both catholyte and anolyte redox species for non-aqueous lithium-based redox flow battery (Li-RFB) applications. The prototype of all-metallocene-based Li-RFB exploits ferrocene (FeCp2) and cobaltocene (CoCp2) as the redox-acti
